Maryland has at least 27 lighthouses, including one replica of a historic lighthouse at Baltimore and a facsimile lighthouse built near Annapolis. In addition, one historic lightship is preserved in Maryland. By my count, 16 of the lighthouses are active. All the lighthouses are on the Chesapeake Bay or its tributaries, since Maryland's short Atlantic coast has no light stations. The two sides of the Chesapeake are known in Maryland as the Eastern Shore and the Western Shore.
